Description
Ignatius has just come back school from the 30th ACM/ICPC. Now he has a lot of homework to do. Every teacher gives him a deadline of handing in the homework. If Ignatius hands in the homework after the deadline, the teacher will reduce his score of the final test. And now we assume that doing everyone homework always takes one day. So Ignatius wants you to help him to arrange the order of doing homework to minimize the reduced score.Input
The input contains several test cases. The first line of the input is a single integer T that is the number of test cases. T test cases follow.Each test case start with a positive integer N(1<=N<=1000) which indicate the number of homework.. Then 2 lines follow. The first line contains N integers that indicate the deadlines of the subjects, and the next line contains N integers that indicate the reduced scores.
Output
For each test case, you should output the smallest total reduced score, one line per test case.Sample Input
333 3 310 5 131 3 16 2 371 4 6 4 2 4 33 2 1 7 6 5 4
Sample Output
035
//看了一些别人的代码，才开始真的地有了一些想法，，刚开始在排序的过程中打算按时间（从小到大）排序的，若时间相同则按分数从大到小排序，结果发现有点小麻烦，有点写不下去的感觉后来就又换了，，感觉按分数排序（从大到小）较为简单，若分数相同，则按时间从小到大排序
#include<iostream>#include<stdio.h>#includeusing namespace std;struct zy{ int day; int score;};bool compare(zy x,zy y){ if(x.score==y.score) return x.day<y.day;//若分数相同，将时间小的放在前面 else return x.score>y.score;//将分数按从大到小排序}int main(){ int T; cin>>T; zy a[2000]; while(T--) { int n,i,j; cin>>n; int flag[2000]={0};//标志无任务 for(i=0;i<n;i++) cin>>a[i].day; for(i=0;i<n;i++) cin>>a[i].score; sort(a,a+n,compare); int sum=0; for(i=0;i<n;i++) { for(j=a[i].day;j>=1;j--) { if(flag[j]==0) { flag[j]=1;//代表第j天有已经有任务了 break; } } if(j==0)//代表任务未完成 sum+=a[i].score; } cout<<sum<<endl; } return 0;}
